According to foreign media reports, a team of engineers at Pennsylvania State University has developed a self-heating battery that can be quickly recharged regardless of the external temperature.

Yang, an assistant research professor of mechanical engineering at Pennsylvania State University, said, "Electric cars are popular on the west coast of the U.S. because of the great climate over there. But once you move an electric car to the East Coast of the U.S. or Canada, then there's a big problem. We demonstrated that these types of self-heating batteries can charge quickly without being affected by external temperatures."

Previously, researchers have developed a battery that can heat itself to avoid power consumption below freezing. Now, suchbatteriesThis principle also applies, and it can even be quickly charged for 15 minutes at -42°C (-45°F).

Wang Chaoyang, professor of chemical engineering, professor of materials science and engineering, and director of the Electrochemical Engine Center, said, "Our battery is unique in that it heats up on its own and automatically switches to charging mode. In addition, there is no need to change the charging station already installed outside - after all, the control of heating and charging occurs inside the battery, not at the charger. And this on-the-go charging allows automakers to equip vehicles with lighter, safer, smaller batteries."

The researchers published the results of their prototype battery tests in the Proceedings of the National Academy of Sciences. They found that the self-heating battery could withstand 4,500 15-minute charges at 32°F with only a 20 percent loss of battery capacity, provide a range of about 280,000 miles, and work for 12.5 years. Tested under the same conditions as theConventional BatteriesLost 20% of battery capacity after just 50 charges.
